As of May 5, the PNSN has located 47 earthquakes near Mount St. Helens since the seismic network was restored on April 21.

I forgot to mention that the last part of their statement is also bad news. As it turns out, heavy snowfall on Mount St. Helens caused their monitoring system to fail. They didn't get it turned back on until April 21. So, there's that.

There are several reasons why it is very unlikely that this swarm is a precursor to imminent eruptive activity at Mount St. Helens—it is similar to ones in the past that did not lead to surface activity; it consists of very small earthquakes occurring at relatively low rates; there are no other geophysical indicators (deformation, tilt, gas) of unrest.
